Hair Follicle Drug Testing - Earlham, IA

What it is, How it works

Hair testing has emerged as a robust method for identifying drug and alcohol consumption. It provides an extended history of substance use by capturing biomarkers within the growing hair strands. Hair collected close to the scalp can reflect a 3-month detection timeframe for alcohol and other substances. It's simple to gather, harder to tamper with, and convenient to transport.

An ideal screening and confirmation sample consists of a 1.5-inch segment of about 200 hair strands (comparable to a #2 pencil), providing 100mg of hair. For tests involving EtG, additional parameters, and/or more than 10 panels, 150mg is recommended. Using a jeweler’s scale for the measurement of specimens is advisable. If scalp hair is absent, a comparable quantity of body hair can be used. "Head hair" refers specifically to scalp hair, whereas "Body hair" encompasses facial, axillary, and other hair types.

Process Overview

The laboratory processing of drug test results includes four primary steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the preliminary step where a sample enters a lab's system; this involves verifying proper sealing and shipping of the sample, assigning a random LAN (Laboratory Accessioning Number), and completing any remaining data not covered by an electronic chain of custody.

Screening performs a preliminary assessment for substance use. While cost-effective for ruling out most cases of drug use, positive screening requires confirmation for legal admissibility. Any presumptive positives identified in Screening need further confirmation.

If Screening results are presumptively positive, additional hair from the sample is prepared for Extraction. In this phase, the concentration of drugs is extracted from hair at much lower levels than in methods like urine or oral fluid testing, which is why hair drug screening poses more challenges.

Confirmation follows any positive screening via methods like GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positives are washed as needed before confirmation. The comprehensive lab process from Accessioning through Confirmation adheres to both the CAP (College of American Pathologists) Hair standards and the ISO / IEC 17025 accreditation.

Advantages of hair drug testing:

• Extended detection period: Hair tests can reveal drug use for up to 90 days, while urine tests have shorter detection times.
• Harder to circumvent: Cheating a hair drug test is notably difficult, increasing result accuracy.
• Chronological data: Provides a timeline of drug use patterns rather than just recent drug intake.

Limitations:

• Delay in detecting recent use: Drugs appear in hair approximately 5-7 days after consumption.
• Expense: Hair drug testing typically costs more than alternative methods.
• Result variation: Factors like hair color and individual hair growth variations can influence drug metabolite concentrations in hair.

Note: While commonly referred to as "hair follicle tests," the evaluation involves the hair strand rather than the follicle beneath the scalp.

What's New In Hair Follicle Drug Testing according to the Hair Drug Testing Experts

With its multidisciplinary nature, hair testing brings together researchers, scientists, and experts from various domains to develop innovative techniques, explore new methodologies, and address emerging concerns, responding to the ever-evolving challenges of drug abuse, therapeutic drug monitoring, and environmental exposures to pollutants.

The joint meeting of the Society of Hair Testing (SoHT) and the Italian Group of Forensic Toxicologists (GTFI) was organized in Verona, June 8–10, 2022, and hosted by the Legal Medicine team of the Verona University Hospital, directed by Franco Tagliaro together with Federica Bortolotti and Rossella Gottardo.

It served as a prominent platform for knowledge exchange and collaboration, facilitating groundbreaking advancements in hair testing and analysis. In this special issue of Drug Testing and Analysis, we aim to showcase the remarkable manuscripts presented at this significant event, shedding light on the latest research and highlighting the future directions in this field.

Novel Analytical Techniques: The Verona meeting witnessed the unveiling of cutting-edge analytical techniques, offering enhanced sensitivity, selectivity, and accuracy for drug testing. Remarkable advancements in sample preparation, detection, and identification of drug compounds have been presented. The manuscripts in this section presented novel approaches, such as multianalyte methods and on-line preparation which can enable rapid analysis and improve thorough forensic investigations.
